Hiya, I have this monitor and it flashes White, Black,Red,Green,Blue,Yellow,Magenta,Cyan comtiuously with only power connected. It appears my daughter has been playing with the buttons looks like it's in some sort of service/test mode. I've tried unplugging and holding various buttons down but to no avail. Any help would be appreciated.

How to fix my Benq Monitor which is scrolling full screens of different colours.

all modern LCDs have ONE and ONE only native screen size. since you did not tell us the model number we have to tell you maybe you are setting the wrong size. if the monitor has worked before then you are sending it the wrong signal.

Hp w2408h monitor flashing red green black blue white

These blinks (flashes) are fault indication. By the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit stage inside the TV. Count the blinks occur at one time switch ON, carefully. Do it once again, and make sure about the number of blinks. If the flashes are continious, non-stop, the main system control IC should be suspected. If you wish to get more details, check the site linked here. It has blinking codes detail to many brand TVs. Pull up older posts. Check the site in 'Mosaic' view. It will make search easy.

Try the plugging the setup into a different monitor to eliminate the lead however it sounds like the monitors died. With cost of screens even if you can get hold of one you'll be better off getting a new monmitor.

How can i play ps2 on lcd without having a black and white screen ? how can i connect the cables ?.....when i look at the back of my lcd i find three ports (red white yellow) when i use them the screen is...

1) The set of input (Yellow= Composite video, Red= Right channel audio, White= Left channel audio). This set of input is for composite video.

2) The set of input (Red= Red video signal, Green= Green video signal + sync, Blue= Blue signal, Red= Right channel audio, White = Left channel audio (the Red and White will be grouped close together). This set of input is used for Component video for HD signal.

You should try using composite video source (Yellow RCA jack) from DVD player and feed to the monitor and see if it works OK with all color showing that way we acn find out if it is the video source problem or the monitor video signal processing problem. Try the PS2 on the TV if it works OK also.

Greenish screen

sometimes speaker magnets or any metallic device can cause this disturbance in this type of monitor. also, if you are using dvi, i would reset all video driver settings to default. this may correct this green tint you are seeing as well. reinstalling the monitor software could have a positive affect.

Green color missing from my LG 700s model

as you are electronics engineer so let us discuss technically.

as you are unable to see green colour means you might be seeing picture of magenta colour

as technically

red+blue = magenta

crt has got three cathodes

your two cathodes circuit is fine one ckt that is green cathode circuit is not working.

for that problem your will have to check

  • cable from computer to monitor
  • loose contact in crt base.
  • crt connector loose
  • voltage on green video output.
  • green video output transistor might be defective.or print loose.
  • circuit related to green video ckt
  • green video signal coming to green video ckt.
  • & finally crt defective (in rare case.)
  • hope this will help
  • good luck.
